Ivalve yeSolenoid

1.Yintoni ivalve ye-solenoid
Ivalve ye-Solenoid yinto ezenzekelayo esisiseko esetyenziselwa ukulawula ulwelo kwaye yeye-actuator;Ayiphelelanga kwi-hydraulic kunye ne-pneumatic.Ivalve ye-solenoid isetyenziselwa ukulawula icala le-hydraulic flow.Izixhobo zomatshini kwifektri zilawulwa ngokubanzi ngensimbi ye-hydraulic, ngoko ke i-valve ye-solenoid iya kusetyenziswa.
Umgaqo osebenzayo we-valve ye-solenoid kukuba kukho indawo evaliweyo kwi-valve ye-solenoid, kwaye kukho imingxuma kwiindawo ezahlukeneyo.Umngxuma ngamnye ukhokelela kwimibhobho yeoli eyahlukeneyo.Kukho ivalve embindini womngxuma, kwaye kukho iimagnethi ezimbini zombane kumacala omabini.Ikhoyili kazibuthe apho icala elenza ivalvu isebenze iya kutsaleleka kweliphi icala.Ngokulawula intshukumo yomzimba wevalvu, imingxunya eyahlukeneyo yeoyile iya kuvaleka okanye ivuze.I-oil inlet hole idla ngokuvuleka, kwaye i-oyile ye-hydraulic iya kungena kwimibhobho ye-oyile eyahlukeneyo, emva koko uxinzelelo lweoyile lutyhala i-piston ye-oil cylinder, eqhuba intonga ye-piston, kwaye intonga ye-piston iqhubela isixhobo somatshini ukuba sihambe.Ngale ndlela, ukunyakaza komatshini kulawulwa ngokulawula okwangoku i-electromagnetic.
Oku ngasentla ngumgaqo jikelele wevalve ye-solenoid
Enyanisweni, ngokweqondo lokushisa kunye noxinzelelo lwe-medium flowing medium, umzekelo, umbhobho unoxinzelelo kwaye i-self-flow state ayinakho uxinzelelo.Umgaqo wokusebenza wevalve ye-solenoid uhlukile.
Umzekelo, ukuqaliswa kwe-zero-voltage kuyadingeka phantsi komgangatho womxhuzulane, oko kukuthi, ikhoyili iya kufunxa wonke umzimba we-brake emva kokuba inikwe amandla.
Ivalve ye-solenoid enoxinzelelo yi-pin efakwe kumzimba we-brake emva kokuba ikhoyili inikwe amandla, kwaye umzimba we-brake ugxothwa ngoxinzelelo lolwelo ngokwalo.
Umahluko phakathi kwezi ndlela zimbini kukuba i-valve ye-solenoid kwimeko yokuqukumbela inomthamo omkhulu kuba ikhoyili idinga ukufunxa wonke umzimba wesango.
Ivalve ye-solenoid phantsi koxinzelelo idinga kuphela ukufunxa ipini, ngoko umthamo wayo unokuba mncinci.
Ivalve ye-solenoid esebenza ngokuthe ngqo:
Umgaqo: Xa unamandla, i-solenoid coil yenza amandla e-electromagnetic ukuphakamisa indawo yokuvala ukusuka kwisihlalo sevalve, kwaye i-valve ivula;Xa umbane ucinyiwe, amandla e-electromagnetic ayanyamalala, intwasahlobo icinezela indawo yokuvala kwisihlalo sevalvu, ize ivalve ivaleke.
Iimpawu: Inokusebenza ngokuqhelekileyo phantsi kwe-vacuum, uxinzelelo olubi kunye noxinzelelo lwe-zero, kodwa ububanzi ngokuqhelekileyo abudluli kwi-25mm.
Ivalve ye-solenoid esebenza ngokuthe ngqo:
Umgaqo: Yindibaniselwano yesenzo esithe ngqo kunye nohlobo lokulinga.Xa kungekho mahluko woxinzelelo phakathi kwendawo yokungena kunye ne-outlet, amandla e-electromagnetic aya kuphakamisa ngokuthe ngqo ivalve encinci yomqhubi kunye nevalve engundoqo yokuvala inyukele phezulu emva kokunika amandla, kwaye ivelufa iya kuvuleka.Xa i-inlet kunye ne-outlet ifikelela kumahluko oqala woxinzelelo, amandla e-electromagnetic aya kuqhuba ivalve encinci, uxinzelelo olukwigumbi elisezantsi levalve enkulu luya kunyuka, kwaye uxinzelelo olukwigumbi eliphezulu luya kuhla, ukutyhala ivalve engundoqo. phezulu ngokusebenzisa umahluko woxinzelelo;Xa umbane ucinyiwe, ivelufa yokulinga isebenzisa amandla asentwasahlobo okanye uxinzelelo oluphakathi ukutyhala indawo yokuvala kwaye yehle ukuya ezantsi ukuvala ivalve.
Iimpawu: Iyakwazi ukusebenza ngoxinzelelo lwe-zero umahluko, i-vacuum kunye noxinzelelo oluphezulu, kodwa amandla makhulu, ngoko kufuneka afakwe ngokuthe tye.
Ivalve ye-solenoid eqhutywayo:
Umgaqo: xa unamandla, amandla ombane we-electromagnetic avula umngxuma wokulingwa, kwaye uxinzelelo olukwigumbi eliphezulu lehla ngokukhawuleza, lwenza umahluko ophezulu kunye noxinzelelo oluphantsi malunga nendawo yokuvala.Uxinzelelo lwe-fluid lutyhala indawo yokuvala phezulu, kwaye i-valve ivule;Xa amandla enqunyulwe, amandla entwasahlobo avala umngxuma wokulingwa, kwaye uxinzelelo lwe-inlet ngokukhawuleza lwenza umahluko woxinzelelo olusezantsi nangaphezulu malunga neendawo zokuvala ivalve ngomngxuma wokudlula.Uxinzelelo lolwelo lutyhala iindawo zokuvala ivalve ukuya ezantsi ukuvala ivalve.
Iimpawu: Umda ophezulu woluhlu loxinzelelo lwe-fluid uphezulu, kwaye unokufakwa ngokusemthethweni (ukwenziwa ngokwezifiso), kodwa imeko yokwahlukana koxinzelelo lwe-fluid kufuneka ihlangane.
Ivalve ye-solenoid eneendlela ezimbini iquka umzimba wevalve kunye nekhoyili ye-solenoid.Sisakhiwo esisebenza ngokuthe ngqo kunye nesekhethi yayo yokulungisa ibhulorho kunye ne-overvoltage kunye nokhuseleko olugqithisiweyo lokhuseleko.
Ikhoyili ye-solenoid ayinawo amandla.Ngeli xesha, i-iron core ye-valve ye-solenoid incike ekupheleni kombhobho ophindwe kabini phantsi kwesenzo se-spring yokubuya, ivala i-outlet yokuphela kombhobho ophindwe kabini, kwaye i-outlet yokuphela kombhobho enye ikwimeko evulekileyo.Isikhenkcezisi siphuma kumbhobho ophuma kumbhobho omnye wevalve ye-solenoid ukuya kwi-evaporator yefriji, kwaye i-evaporator yesikhenkcisi iqukuqela ibuyele kwicompressor ukuqonda umjikelo wefriji.
Ikhoyili ye-solenoid inamandla.Ngeli xesha, umbindi wentsimbi yevalve ye-solenoid yoyisa amandla entwasahlobo yokubuya kwaye ihambe iye kwisiphelo sombhobho omnye phantsi kwesenzo samandla ombane we-electromagnetic, ivale umbhobho omnye wokuphuma kokuphela, kwaye umbhobho ophuma kabini wokuphuma ukwindawo evulekileyo. urhulumente.Isikhenkcezisi siphuma kumbhobho ophuma kabini wokuphela kombhobho wevalve ye-solenoid ukuya kwi-evaporator yefriji kwaye ibuyela kwicompressor ukuqonda umjikelo wefriji.
Ivalve ye-solenoid eneendlela-ezimbini yenziwa ngumzimba wevalvu kunye nekhoyili ye-solenoid.Isakhiwo esisebenza ngokuthe ngqo kunye nesekhethi yokulungisa ibhulorho kunye ne-overvoltage kunye ne-overcurrent yokukhusela ukhuseleko А?Br>Ukusebenza kwe-1 kwinkqubo: i-coil ye-solenoid ye-valve ayinamandla.Ngeli xesha, i-iron core ye-valve ye-solenoid incike ekupheleni kombhobho ophindwe kabini phantsi kwesenzo se-spring yokubuya, ivala i-outlet yokuphela kombhobho ophindwe kabini, kwaye i-outlet yokuphela kombhobho enye ikwimeko evulekileyo.Isikhenkcezisi siphuma kumbhobho ophuma kumbhobho omnye wevalve ye-solenoid ukuya kwi-evaporator yefriji, kwaye i-evaporator yesikhenkcisi iqukuqela ibuyele kwicompressor ukuqonda umjikelo wefriji.(Jonga umfanekiso 1)
Imeko yokusebenza ye-2 kwinkqubo: icoil yevalve ye-solenoid inikwe amandla.Ngeli xesha, umbindi wentsimbi yevalve ye-solenoid yoyisa amandla entwasahlobo yokubuya kwaye ihambe iye kwisiphelo sombhobho omnye phantsi kwesenzo samandla ombane we-electromagnetic, ivale umbhobho omnye wokuphuma kokuphela, kwaye umbhobho ophuma kabini wokuphuma ukwindawo evulekileyo. urhulumente.Isikhenkcezisi siphuma kumbhobho ophuma kabini wokuphela kombhobho wevalve ye-solenoid ukuya kwi-evaporator yefriji kwaye ibuyela kwicompressor ukuqonda umjikelo wefriji.
